Wikipedia

I learned the hard way never to use wikipedia as a citation during online scientific debate, as on two occasions the person I was debating simply went and edited the page I cited to say something different. The pages were on Classical Mechanics and Exothermic Reactions and the vandalism to the latter has never been undone, making the page factually inaccurate to this day. I suppose the place is fine for stuff like the history of Harry Potter, but for science? No - it is completely unreliable and not to be trusted.

Quora

Absolutely useless for any scientific or technical subject, with most answers provided by fake Indian science Phd's who can barely write in English and don't even understand how Force Vectors work..There is no way that these clowns are accredited experts in their fields, and thus I can only conclude the site is a total fraud. Likeliest reason is the site is compromised by Silicon Valley venture capitalists to enable the pushing of fake tech like Theranos, Hyperloop, etc.

Stack Exchange

Not a good place for novices as the best answers are often downvoted whilst the worst rise to the top. If you have no knowledge of the subject you are asking about you will not notice this and end up being misinformed. However, if you are already familiar with a subject and just want further specific details, it can be useful as there are some good, knowledgeable contributors. Put bluntly, there are too many geeky sci-fi fans posting on hard science and engineering subjects they have zero experience of, who get angry when corrected on their ignorance and downvote their superiors.. Poor moderation allows this behaviour to prosper.

Fakeologist

Tries to convince you everything and everyone is fake so you look insane if you talk about it IRL. Alleged owner is prolific e-beggar. Has at most four contributors using sockpuppets and voice morphing tech to seem like more. Makes podcasts that go on for hours whilst saying nothing and enforcing bleak nihilistic worldview.Original pusher of ridiculous flat earth and transvestigation psyops. Do not give money, do not join discord. Military intelligence connections, likely Five Eyes Alliance/NATO.

John Le Bon

Predatory pseudonymous Stefan Molyneux copycat and e-beggar who hides his non-existent 'world leading research' behind paywall. Uses sockpuppets to pimp his wares on reddit, youtube etc, and passive-aggressive sophism to defend his lack of substance. Has no original ideas and does not understand simplest scientific terms. Textbook sociopath. Do not give him money.

The Flat Earth Society

Pretends to be a free thinkers forum but is in fact run by a deranged ex-military Australian pensioner, a cyberbullying NASA shill from Bradford England, and one or two unidentified others, via persona management software, all likely blackmailed. Is currently trying to emulate Godlikeproductions level of data mining and mind control but does not have the resources. Has no genuine members, so do not open PMs from anyone if you join as they will be manipulative/filled with malware. Avoid.
